Only 55Mb on a 70Mb internet connection

Sat Oct 06, 2012 12:34 am

Hi, I have a fiber optic link which I recently upgraded from 50Mb to 70Mb, the problem is that all I can see is 55Mb. The company that provides the service came and ran tests to saturate the link and check if the speed was correct and they got 70Mb perfectly , if I connect directly to the switch that is connected to the link and I assign a static IP I can see the 70 Mb but once I connect to my server IBM Xeon Quad Core with Mikrotik as much as I can see the link is 55Mb. Even if I connect two network cables between the server and the switch and balance the traffic between the two links it does not pass the speed of 55Mb.

I have others links wich I use for load balancing normally, if I put all the links to work my internet average consumption is around 75Mb but if I redirect the traffic to the fiber it does not exceed 55Mb. I reviewed the configuration of the Mikrotik but can not find anything that could be limiting this, any ideas?

what kind of ques does your interface have? Try use only hardware, and ethernet default. If its just a default route to internet, you should be able to get about 70Mb from an old RB532.

Thanks for the reply, it´s a IBM xeon quad core with mikrotik 5.20. The queue for the interface is ethernet default, I can't change it to only hardware because it gives me an error message that only hardware queue is not supporyed for the interface.

Use fast ping to hunt for packet loss and delay that may interfere with TCP.

After you read this http://wiki.mikrotik.com/wiki/NetworkPr ... of_Service do you have any additional questions?

Thankyou that really helped to find the solution, the problem was on my service provider side, thanks!
